COMBINED SIMMERER AND FLASH-IGNITER FOB. GAS-STOVES.

i following is a full, clear, and exact description thereof.

The present invention relates to new and useful improvements in gas Stoves and is directed more particularly to the simmering burner and flash igniter structures thereof.

It is primarily the object of the present invention to combine the flash igniter structure and the simmering burner structure of a gas stove in an exceedingly simple and compact manner, and further in a manner wherein the flash igniter structure is carried entirely by and housed within the simmerin burner structure.

lhepresent invention contemplates the provision of a combined valve structure for the'simmering burner and the flash igniter burner, andin this connection it is further an object of the present invention to utilize this valve arrangement as a master valve control for the flash burner valve structure whereby this master valve may be actuated to entirely shut oif flow of gas through the flash igniter structure, providing more particularly for shutting oil' the usual pilot light of the flash igniter, it being appreciated that, although a valve is usually associated with the pilot light by-pass, this Fi ure l is an elevational view of a com-y bine flash igniter and simmerer constructed in accordance with the present invention, with the valve and portions of the burner structure in section.

Fig. 2 is a transverse sectional view through the valve structure on the line 2-2 of liig. 1 showing the simmering burner valve ports.

Fig. 3 is a similar sectional view through thatportion of the valve structure including the 1gniter burner valve ports as indicated by the line 3--3 of F ig. 1.

Fig. 4 is a top plan view of the burner head structure. l

Referri g n0w..more particularly to the accompan ing drawings, the combined valve structure includes a main casing 5 having lts bore taperingly reduced toward its lower end in the usual manner of gas stove valves for the reception of a similarly tapered valve head 6 to the lower end of which is secured the handle 7. ,Extended from one side of the casing is a nipple 8 whereby the casing is secured to the usual main suppl pipe 9 at the front of the stove and extendi-I ing from the opposite side of the casingis a boss 10 for the securement of the burner supply pipes.

This valve head controls the flow of gas to the simmering burner, and it also comprises a master valve for the igniter valve structure, which valve structure is preferably Qf the type embodied in my lformer application for patent filed April 14, 1916, Serial No. 91125, wherein is provided a plunger valve and by-pass valve which are embodied in a single unit detachable from the casing and in the present instance the main valve 6 serves as a casing, being provided with a well 11 extending downwardly through its major portion which is threaded to receive the plunger valve cage 12. The lower end of this cage forms a valve seat engageable by the head 13 of the plunger valve, whose stem 14 'extends upwardly through the cage and terminates in the button 15, the head 13 being normally urged to closing position by a spring 16 disposed within tie upper portion of the cage and bearing against the button and against a suitable gasket means within the cage.

The intermediate peripheral portion ofthe cage is cut away to form, in conjuction with the adjacent well wall portion, an annular chamber 17 which communicates with the interior of the cage. The by-pass arrangement embodied in this igniter valve structure comprises a longitudinal passage 18 through the valve head 13 and stem 14 which communicates with the interior of the cage by a lateral port 19 in the stem. Disposed in the longitudinal passage is a valve pin 20 which extends below the port 19 and which has one side portionadjacent and below the said port out away to provide a passage communicating with the port and adjustable upon rotation of the stem to regulate the flow through the by-pass.

The boss l() of the main casing is offset upwardly from the nipple 8, and extending through the nipple 8 are inlet and outlet simmering supply ports 21 and 22 respectively, which are adapted to aline with openings 2la and 22 respectively formed in the adjacent wall portion of the main valve head 6, the opening 2la being extended transversely in the wall whereby to permit access of gas into the well of the main valve head, when the outlet port 22 is shut ofi'. Above the outlet port 22 a flash supply port 23 is formed in the casing and boss 10, which port at its inner end is normally in alinement with a transversely elongated opening 24 formed in the adjacent wall portion of the main valve, this opening 24 being inv communication with the annular chamber 17 of the igniter valve.

Thus in the normal manipulation of the valve head 6 to open and close the simmering burner outlet port 22, the main inlet port 2l and the flash burner outlet port 23 are at all times open to permit independent operation of the flash burner valve. The valve head 6 is normally held within such limits of rotation as to retain the above mentioned relation by a pin 25 projecting laterally from the upper portion of the valve head to engage in a suitable cut away portion of the casing for abutment with the sides of said cut away portion, this cut away portion of the casing being coextensive with the transversely extended opening 21a of the main valve head 6.

It is seen that movement or' the valve head past its normal limits of movement will shut ofi the main supply port 21, to consequently shut olf flow also through the flash burner valve structure. Thus the valve 6 may serve as a master valve for the flash burner valve structure, which comprises an auxiliary valve means in the main valve. and which includes the main flash valve and the by-pass valve. To procure this complete shut ofi' operation of the valve 6, the pin 25 may be removed or suitably adjusted with respect to its relation to the valve head and the cut away portion of the casing.

The simmering burnerv of the present invention comprises a flat top wall 26 provided adjacent its periphery with a series of jet apertures 27' and depending side walls which merge into a lateral neck portion 28 in which is threadedly engaged one end of the simmering burner pipe 29, the other end of which pipe is slidably engaged on the boss 10. Threaded in the upper portion of the boss to communicate with the flash burner is a flash supply pipe-30 and this pipe extends through the pipe 29 and has its end curved upwardly within the simmering burner and extended through the top wall thereof adjacent one side for threaded engagement with the flash burner head 31, a suitable stop nut 32 being provided on the pipe within the simmering burner to bear against the top plate thereof whereby a firm securement of the flash burner to the simmering burner may be had. In assembling this structure the flash supply pipe 30 is extended into the simmering burner and secured by attachment of the flash burner head 31, the .simmering supply pipe 29 is then threaded into the simmering burner and the flash burner` supply pipe is threaded into the boss 10, while the adjacent end of the simmering supply pipe slides over the said boss.

To provide for proper admixture of air with the gas in the simmering supply pipe, said pipe is provided in its lower portion adjacent the boss 10 with an air port 33 and the adjacent end of the simmering outlet port ol' the valve is restricted to form a nozzle. Thus gas is supplied to the simmering burner' at a pressure but slightly above atmospheric pressure, while the gas supply to the flash burner is at the pressure of the gas main, whereby flames may be projectedby the flash burner a suflicient distance to ignite the various main burners of the stove.

To provide a shield for the pilot light of the flash burner, an arcuate upstanding shield plate 34 is secured at the front portion of the simmering burner by attachment to upstanding peripheral lugs 35 thereon and this plate is provided with ports 36 in alin'ement with the forwardly disposed main burners and their respective flash burner apertures. The upper portion of this shield plate carries an inwardly extending top wall 37 which, at its intermediate portion projects over the flash burner to protect it from drippings. Inasmuch as drafts do not usually occur from the back portion of a stove due to its normal positioning against the wall, the present shield structure serves to efficiently guard against such drafts as would tend to blow out the pilot light.

The present arrangement occupies but little more space than either the simmering burner structure or the flash igniter structure alone and consequently conduces materially toward a desired compactness of stove structure, in addition to the provision of a central positioning of both the simmering and flash igniter burners and a master valve control for the flash burner valve.
